Diameter of crank pin of centre crankshaft at TDC position given width of crank web Solution

STEP 0: Pre-Calculation Summary
Formula Used
Diameter of Crank Pin = Width of Crank Web/1.14
dcp = w/1.14
This formula uses 2 Variables
Variables Used
Diameter of Crank Pin - (Measured in Meter) - Diameter of crank pin is the diameter of the crank pin used in connecting the connecting rod with the crank.
Width of Crank Web - (Measured in Meter) - Width of Crank Web is defined as the width of the crank web (the portion of a crank between the crankpin and the shaft) measured perpendicular to the crankpin longitudinal axis.
STEP 1: Convert Input(s) to Base Unit
Width of Crank Web: 65 Millimeter --> 0.065 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
dcp = w/1.14 --> 0.065/1.14
Evaluating ... ...
dcp = 0.0570175438596491
STEP 3: Convert Result to Output's Unit
0.0570175438596491 Meter -->57.0175438596491 Millimeter (Check conversion here)
FINAL ANSWER
57.0175438596491 57.01754 Millimeter <-- Diameter of Crank Pin
(Calculation completed in 00.004 seconds)

What is a Crankshaft?

The crankshaft of an engine is mechanical equipment whose main function is to convert the Linear motion of the Piston to Rotational Motion. The reciprocating motion of the piston is transferred to the crankshaft through Connecting Rod. A crankshaft has crankpins, crank webs, balancing weights, and main journals. The big end of the connecting rod is connected to the crankpin of the crankshaft. In a 4 stroke engine, one complete rotation of the crankshaft takes place in two strokes of the piston.
A crankshaft has the following main parts :
1. Crankpin
2. Main Journals
3. Crank Web
4. Counterweights
5. Thrust Washers
6. Oil passage & Oil Seals
7. Flywheel Mounting Flange

What is a crank arm or crank web?

The crank arm is also known as web or crank web. The Crank web is one of the most important parts of a crankshaft. The main purpose of a crank arm or crank web is to connect the crankshaft to the main bearing journals. A crank web is positioned opposite to the crank pin.
